Update saturation limit for ETMX/Y and TMSX/Y with new 20 bit dacs for LLO
The ETM and TMS suspensions are now using 20 bit dacs at LLO for all stages, so the saturation limit will need to be updated accordingly in the lockloss script
Maintenance will be performed on git.ligo.org, containers.ligo.org, and docs.ligo.org on Tuesday 24 March 2025 starting at approximately 8:30am PDT. It is expected to take around 30 minutes and there will be several periods of downtime throughout the maintenance. Please address any comments, concerns, or questions to the helpdesk.

@camilla.compton would you know how to fix this for LLO, or who to assign it to ? The most recent lockloss saturations limits are out of range, probably because of wrong dac settings. See example below :
Thanks for brining this up and reminding us Arnaud, @austin.jennings and I can get this sorted this week and check on the status of !102. @arnaud.pele are these the only suspensions at LLO with new 20 bit dacs?
We also have this new alog 66836 from Jeff with an update of LHO 20-bit DACs.
From Stuart at LLO : "I believe Keith aims to have the last 2 remaining front-ends (L1SUSH2B and L1SUSH56) swapped to 20-bit DACs for O4. I think he is awaiting delivery of 20-bit DACs. So this includes a strange mix of the IM's RM's OMC SR3 and top 2 stages of SRM are still on 18-bit DACs at the moment for LLO."
So currently all suspensions are on 20-bit DACs, except for the ones listed above.
